www.morebeer.com If you want professional at a homebrew scale. Many US craft brewers use their "brew sculptures" as pilot systems. Three variations available. All include hot liquour tank, mash/lauter tun, and boil kettle.

Quite a waste of money if you ask me. I use one burner and a single mash/lauter/boil tun. I can do decoctions, parti-gyles, multi-rest mashes quite easily. Just need a second vessel as a holding tank as the situation requires.

Forget about the brewhouse though. Terribly over romanticized. Its very easy to make nice wort. Its all about the yeast. The finest wort ever made will make shit beer under poor fermentation conditions.
